Should we, for the same reason, ban the common substances used to make meth?

I'm not a huge gun control advocate, but the point you're making is weak.

The point is mostly about the lunacy that getting guns out of the hands of legal people will somehow limit the access of guns to illegitimate.

But to the point of banning common substances for meth, etc...

Well the State Department functionally already ordered the 'ban' of information(in this case the plans used to build a 3D printed gun). Frankly that should be a concern for everyone regardless of what the information being prohibited is.

Will we next scour old medical journals and demand they be taken offline if they contain formulas for psychoactive chemicals that have yet to be declared illegal? It's not a huge leap from what has already happened an is a fairly bad slippery slope.

Part of the point about this is also around some of the irrational fear of 3D printed guns etc....for instance the stapler based shotgun is significantly cheaper to make and far more effective than a 3D printed gun firing a single shot 22.
